Maximizing the signal: LNB polarization?

[JetSetTed]

Hi,

I'm trying to use a old Sky minidish to access Astra 1@19.2°E to receive FTA German DVB-S.

My first problem is getting the dish in the right place. I note from the Astra site that Astra 2 (where Sky Digital is), the LNB polarization is a around 6° different from that for Astra 1. Does this make a big difference to my signal strength? I can't see how to adjust the LNB polarization anyway.

Scanning the cluster at 19.2°E is finding channels on 1KR and 1L, but so far not on 1H, which is the satellite carrying the interesting German transmissions. I'm presuming that I'm simply not getting any signal from that member of the cluster because I'm not yet finely enough adjusted. Is this belief correct?

Thanks,
JST

Welcome,

The two satellites are 9° apart (AZ / left to right movement). You maybe getting confused with LNb polarisation / skew setting.

The skew difference between these two bird would have hardly no effect at all but to adjust this you can rotate the LNb within it holder to maximise cross polar effect also known as 'cross polar null'

Astra 19.2e is easily achievable with a Sl<y mini-dish.

Yes, thanks for that. The skew difference is only about 6°, which I've realized is the same as the difference between one second and the next on a watch face.

Iäd better look again at my azimuth and elevation -- I seem to be getting only a couple of members of the 19.2°E cluster, not the whole hog.

Cheers,

Check http://www.lyngsat.com/astra19.html for transponders and coverage maps.

Also check LNb setting on receiver (should be set to universal 9750 / 10600).

This would only give you certain channels if in correctly set so important to check
